    Rotational Motion
    This rotation was not extremely difficult. 1) write down or print all of the formulas from the wiki and there are some in the physics book. 2) make sure you are answering what the question is asking for. Some questions look and are set up the same but are asking for different things (check before you put the answer in :/ ) 3) CHECK YOUR UNITS I misses several questions because I answered in rev/s and it asked for rad/s or I answered in cm and it was asking for m. BE CAREFUL. DO NOT PROCRASTINATE :)

    Good luck!

    Okay this packet isn't exactly as hard as you would think and expect it to be. The equations on the wikispaces is a HUGE help along with looking in the High school text book. A lot of the equations in that book are the majority of what you will use. Look in chapter 12 and chapter 13. Make sure you read the questions carefully and tell if it says OPEN pipe or a CLOSED pipe. Another thing make sure you ASK MS. DUNCAN. If it doesn't give or tell you the harmonic number assume its in the first harmonic. With the question about the jet plane look in the High school book on page 490 with a chart to get the power. Don't fret over this packet. Have fun and good luck.

    Dynamics
    This being the first unit I had, you would think it would be quite simple considering the fact that we just finished free body diagrams, something that involves solving for the same variables that this packet requires. You use the same formulas such as Fnet=mass*acceleration and others that are involved in solving for forces. A few of these problems are more difficult, such as the problem that has three blocks. A hint is to think about it first as one whole block, then look at each individual block's forces.
    The elevator problems are quite simple: there is a video on the wikispace. The Atwood machine problems are simple as well; the video on the wikispace helps on that as well. I used another video on youtube:
